Abstract: Microphotonic
circuits based on strong confinement raise the prospect of dense photonic
integration on a chip, highly energy efficient on-chip communication links, and
of novel device concepts based on unique device physics and topologies that
become practical in this regime, including optical nonlinear effects and
optical forces. In this talk, I will
describe the demonstration of telecom-grade filters and hitless wavelength
switches in strong-confinement microphotonics. I will also talk about device concepts based
on localized destructive mode interference and a new, unidirectional guided
Bloch wave, that enable efficient waveguide crossings, modulators, and other
optically efficient contacted structures.
I will describe recent efforts to integrate silicon photonics with
advanced CMOS electronics in the front end CMOS process, and will show the
first demonstrations of photonic devices in 65nm and 32nm CMOS technology with
no process changes, compatible with microprocessor grade state-of-the-art
CMOS. These developments are the first
results of current research on deeply integrated photonics in both processor
and DRAM technology.
